We divide 777840 by 79
We want to figure out the number of times 777840 can be divided by 79.

On to step 1:
When dividing 7 by 79, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 79

Advancing to step 2:
When dividing 77 by 79, we get 0 with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Include the next digit (7) from the dividend after 77, then repeat: 777 / 79

On to step 3:
777 divided by 79 is 9 with a remainder of 66.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 711 from 777 to get 66.
Bring next digit (8) of the dividend behind the 66 and repeat the process: 668 / 79

On to step 4:
The number 79 fits into 668 8 times, leaving a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 98.0
The remainder is 36 after subtracting 632 from 668.
Include the next digit (4) from the dividend after 36, then repeat: 364 / 79

Moving on to step 5:
79 goes into 364 4 times with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 984.0
Subtracting 316 from 364 leaves us with 48.
Fetch the next digit (0) from the dividend, attach it to 48 and continue: 480 / 79

Moving on to step 6:
79 goes into 480 6 times with a remainder of 6.
The next digit of our result is 6. 
Result so far: 9846.0
Subtract 474 from 480 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
The number 79 fits into 60 0 times, leaving a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 9846.0
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 8:
79 goes into 600 7 times with a remainder of 47.
The next digit of our result is 7. 
Result so far: 9846.07
Subtract 553 from 600 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 9:
79 goes into 470 5 times with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 9846.075
Subtract 395 from 470 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 10:
If we divide 750 by 79, we get 9 and a remainder of 39.
Put 9 as the next digit of the answer. 
Result so far: 9846.0759
Subtracting 711 from 750 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 11:
If we divide 390 by 79, we get 4 and a remainder of 74.
Put 4 as the next digit of the answer. 
Result so far: 9846.07594
Subtract 316 from 390 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 12:
79 can be fit into 740 9 times, resulting in a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 9846.075949
If we subtract 711 from 740, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 13:
If we divide 290 by 79, we get 3 and a remainder of 53.
Write down 3 as next digit of the result. 
Result so far: 9846.0759493
Subtract 237 from 290 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 14:
When dividing 530 by 79, we get 6 with a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 9846.07594936
If we take 474 away from 530, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

After the division, we end up with 9846.07594936 and a remainder of 5.6e-08.
